In a story as bizarre as it is deja vu-ish, a 44-year-old fetus has been found in an 84-year-old Brazilian woman.

The Daily Mail reports by way of G1 that the discovery came last Friday, when the woman's intense stomach pains landed her in a hospital in Tocantins state in central Brazil. X-rays revealed the unthinkable: a "stone baby."

As the International Business Times explains, the rare phenomenon is known as lithopedion, in which the fetus grows and then dies outside of the uterus.

With the body unable to rid itself of it, the dead fetus is instead covered in calcium as a means of protection, resulting in the "stone baby."
